Batch Water Adjustment with measured batch water added or planned of 50 gal or L: a worked example

This worked example runs the batch water adjustment numbers for a tougher week than the baseline: measured batch water added or planned of 50 gal or L instead of the typical 100 gal or L. Adjust concrete batch water for aggregate moisture, absorption, and mix-design target water.

The inputs for this scenario

  • Measured batch water added or planned: 50 gal or L (the input this scenario stresses; the baseline uses 100)
  • Water correction multiplier from moisture and absorption: 1.04 x (held at the documented default)
  • Target batch water for the mix design: 104 gal or L (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Batch Water Adjustment = measured batch water added or planned × correction multiplier.
  • Batch Water Adjustment works out to 52 gal or L water at these inputs, and this is the headline figure for the scenario.
  • Batch Water Adjustment gap to target works out to -52 value at these inputs.
  • Measured batch water added or planned works out to 50 value at these inputs.
  • Water correction multiplier from moisture and absorption works out to 1.04 x at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where measured batch water added or planned sits at 100 gal or L and the headline result is 104 gal or L water, this scenario comes in 50% below the baseline at 52 gal or L water.
  • Use it at the batch panel when aggregate moisture changes and you need to verify corrected water still hits the design target. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Batch Water Adjustment: 52 gal or L water (headline result)
  • Batch Water Adjustment gap to target: -52 value
  • Measured batch water added or planned: 50 value
  • Water correction multiplier from moisture and absorption: 1.04 x
